The opening as it read in 2005

Matrilineality is a system in which one belongs to one's mother's lineage.1 It may also involve the inheritance of property or titles through the female line. However, the latter does not always hold; in some societies, titles or property went to the male heir (s) of the nearest female relative . (Basically, two such forms are: 1. from uncle to nephew, and 2. from grandfather to grandson.)2
